IT HAS BEEN ARGUED that the vectorcardiogram should yield no more information than a standard 12-lead electrocardiogram. Yet many authors, including Wolff," 2 Burch,3-5 Scherlis and Grishman6 and Milnor,7 employing different lead systems, have published data indicating that the vectorcardiogram may demonstrate abnormalities not apparent in the electrocardiogram. Of a total of 2,545 vectorcardio...

Vectorcardiography demonstrates very clearly the method of auricular activation and shows its spatial development. This is illustrated and discussed in this paper as it occurs in normal subjects, in a patient with an ectopic auricular pacemaker, and in patients with pulmonary heart disease. Changes similar to those seen in patients with cor pulmonale have been observed in dogs after partial occ...
